You are quite confused!.. regarding that quote and what you said after. Does this clear it up: gravity is not a force, it is an acceleration, 9.8m/s2.
Agreed, Italia. My point is, it is an acceleration just like any other acceleration. If an aircraft is under a load of 2g, it is undegoing an acceleration of 19.6m/s2. F=M*A so so the airccraft is under a force of M*19.6. This force can be described as it's weght, as there is no way of descerning which part of the force is "Real" wieght and which is "Apparent".
This discussion is filled with ridiculous banter... going back to PBLs dilemma, no one has mentioned one thing about the gravity equation while trying to explain gravity.
The Gravity Equation quantifies Gravity. It doesn't explain it.
As to this-
but you can have a force without acceleration!!!
No, you can't. You are confused on that one.Force is measured in kg*m/s2.If you dont HAVE any m/s2, you don't have a Force! Please describe a net force that does not produce an acceleration.
